[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cleaning interdental plaque and a device for irrigating the oral cavity, which has a gingival massage effect.

[0002]

[Technical background of the invention] According to a survey by the Ministry of Health and Welfare (1987), 80% of Japanese aged 35 and over have some gingival findings, and 80% of those aged 40 and over lose their teeth because of periodontal disease It is. Plaque adheres to the tooth surface, and endotoxins, enzymes, and bacterial products from the plaque stimulate the gums and cause inflammation (gingivitis). If the gingival tissue is further destroyed and inflammation reaches the bones supporting the teeth, periodontitis (so-called alveolar pyorrhea) results. The cause of periodontal disease originates in plaque, but it is difficult to remove plaque particularly in the interdental region by a normal brushing operation. For this reason, it has been recently concluded that the reason for the high rate of periodontal disease, despite the fact that there are no Japanese who do not brush their teeth, is "particularly poor plaque removal in the interdental region".

[0003]

2. Description of the Related Art Based on the technical background as described above, a number of dental plaque removing articles such as electric toothbrushes, mouth washer, dental floss, and interdental brushes have been developed in recent years due to the increasing awareness of oral care. . (A) The electric toothbrush is more expensive, as it is difficult to remove plaque in the interdental region as well as a general toothbrush, and has a disadvantage that it is relatively quick to move and thus easily damages gums. (B) Since the mouth washer is used by connecting it to the water tap of the washroom or jet-washed by an electro-arterial pump, it can be used only in the washroom and can be carried and used at any time. Absent. In addition, since the discharged washing water constantly spills out of the mouth, it is disadvantageous in that it is not operationally limited, is limited to use in a washroom, and is expensive. (C) Dental floss is not only troublesome especially for back teeth, but also cannot be used for bridge teeth. Also,
There are drawbacks such as easy breakage of crowns and fillings. (D) The operation is troublesome for the interdental brush. In addition, brushes of various sizes and shapes are required, and there is an economical problem that the brushes are easy to bend and hard to last.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device which has a simple structure, in which bubbles are alternately mixed into a fluid jet to generate pulsation, thereby improving cleaning efficiency, and at the same time being portable and low in cost. It is in.

[0005]

Means for Solving the Problems The above object is for oral washing
In a washer equipped with a discharge pipe that sprays liquid for cleaning
Te, provided with a pressure device of the internal gas in a sealed container which enables replenishing the liquid in the closed container, the liquid suction pipe having a suction port of the pressurized air that is not closed by the liquid level is provided, the discharge end of the liquid suction pipe, connect the discharge pipe with an injection-off valve, the same pressure
Pressurized water and compressed air into the liquid suction pipe
This can be achieved by doing so.

[0006]

[Effect] The momentum is mass × velocity, and the temporal change of the momentum is the washing pulse power. The mass difference between the liquid and the gas bubbles is about 1000 times, which provides a very effective cleaning action. By including air bubbles, the amount of the discharged liquid and, consequently, the amount of drainage can be reduced. When applied to the fixed-rate discharge pump mechanism,
Because you can aim and spray where you need it when you need it,
There is no busyness at the time of use. In addition, portability is improved.
Furthermore, by pre-pressurizing the air in the container,
Cleaning between teeth can be performed only by opening and closing the injection valve.

[0007]

Next, the details of the embodiment of the present invention will be described with reference to the drawings.

Reference numeral 13 shown in FIG. 1 denotes a closed container, and a liquid supply port 15 having a closed lid 14 is provided on one side of the upper portion of the closed container 13. An electric or manual pressurizing device 16 is provided at the upper part of the closed container 13 so that pressurized air is supplied to the upper part of the closed container 13. Reference numeral 17 denotes a "-shaped liquid suction pipe provided on one side inside the closed container 13, and the lower end of the vertical portion of the liquid suction pipe 17 is opened close to the bottom, and the upper end is outside the upper end side wall of the closed container 13. A base of a flexible pipe 18 is connected to the upper open end, and a discharge pipe 20 having an injection opening / closing valve 19 as a base is connected to the other end of the flexible pipe 18. 2, a suction port 21 for pressurized air is formed above the liquid suction pipe 17, that is, above the liquid level .
Liquid suction pipe 1 with compressed water and compressed air of the same pressure
7 is introduced .

[0009]

[Explanation of operation] The closed lid 13 is removed and the closed container 13 is removed.
The inside of the container is filled with water to a level lower than the pressured air suction port 21, and after the closed lid 14 is closed, the pressurized device 16 is operated electrically or manually to supply the compressed air into the closed container 13. . At the time of cleaning between teeth, pressurized air / liquid flows toward the discharge pipe 20 by opening and closing the injection opening / closing valve 19 by directing the tip of the discharge pipe 20 between the teeth, and during this time, the kinematic viscosity coefficient of the gas and the liquid is reduced. Air bubbles are automatically dispersed in the discharge pipe 20 due to the difference and the effect of surface tension,
In a, a liquid pulse stream having a cleaning effect is generated to clean the space between teeth.

[0010]

[Effect of the Invention] As described above, according to the configuration of the present invention,
The following effects can be obtained.

[0011] The cleaning effect between teeth and the like by the gas-liquid pulse flow effect is efficiently performed, and by applying it to gums and the like, an appropriate massage effect can be obtained, and the health of gums and the like can be preserved.

By including bubbles, the amount of the discharged liquid can be reduced.

By accumulating the pressure in the closed container, the cleaning operation between teeth and the like by the continuous gas-liquid pulse flow effect can be efficiently performed by simply opening and closing the injection on-off valve.
